* anism partly OSCAR KNQEPYE, Ell-311W To at w/wm at may concern:

Be it known that 1, Oscar Knorr, a citizen of the United States of America, resirling at Flint, in the county of Genesee and State of Michigan, have invented certain new and useful Improvements in Antoniobile Door-Locks, of which the following is a specification, reference being haol therein to v the accompanying drawings This invention relates to an automobile door lock, and more particularly so a novel latch by which an automobile door or any other door may be held in a closed position ancl at the same time compensate for expansion and contraction oi latch elements or any inequalities between a door anti oloor frame caused by vibrations or loose fitting.

The object of my invention is to provide a simple, durable and inexpensive latch of the, above type possessing the above men-- tioned characteristics (1,116. others which make the latch particularly apglicabie to an automobile door. The latch mechanism. is of such construction that the parts thereot can be easily and quickly assernbiecl and embodied in a door structure to be opera e-ti trom the upper edge of the door or at an); convenient place upon the same.

The mechanical construction entering my improveel latch will .be hereinafte" 23ocifically described. and then clairnetl, reference will now be hatl to the drawin wherein- Figure 1 is an elevation of the latch niechbroken away; Fig. 2 is a plan of the same, partly broken away and, partly, in section, showing the mechanism in connection with a door frame and door; Fig. 8 is a perspective view of a detacherl latch member or bolt; Fig. 4. is a similar view of a detached strike plate and keeper, and 5 is a perspective View of a cloor frame plate illustrating a modification of my invention In the drawing, 1 denotes a door having a rabbetecl edge 2 and door at the rabbeteol edge thereof is cut away as at and 4, to provide clearance for a latch member or bolt 5 and an oblong casing The oblong casing 6 forms part of a face plate 7 providetl'with openings 8 ad opted to accommoclate screws or other fastening means whereby it may be conveniently securerl to the inner side of the door 1. The latch member or bolt 5 is sliclable in the casing t3 and the upper and lower GClgQS ct saicl latclmember have notches 9 and 10. The

inner sicle of the plate indoor 1 15; cut away to oro ioe provioes 'leaiance lever 1' fulcruinetl upon the upper end oi said lever whic to extend. to upper edge whereby it may be moved to sh t the latch 'rneinber or bolt 5- The lower or short arm of the lever 11 is held norznall against upstruclr or 13 of the 'Z by spring l-i on the inner sie'oi the face plate 7 sairl spr'" j restoring said lever to normal "position 2 having moved to shift the niember'cr bolllilxtencling into notch it) of member bolt 5 no! of a ooilecl spring 1! of the face plate spring holcline th normally r the cas ieznher o' curl o latch nienil 7 shaped. nering h a v LJ bill The hoolr or bolt can be easil support garnet verticv TFL. rt- 1 .m 11.6 ire-6185 latch member or bolt cope to lock thetloor in a closed position The construction oi the keeper Z1 is such as to provicle a recess 2e which the hill encl of: the latch member or bolt may rilie or vibrate without the bill ricling out of the opening 23 consequently the rloor i. cannot accidentally open tine any vibrations.

In there illustrated a portion of an automobile tloorwa v having a metallic plate 25 provicleci with a lree er at, such plate and keeper being anplicable to cloors anti doorways are not rabbete as shown in Fig 1, v

it is thought that the operation utility the lloor latch will be apparenwithout rther description, ancl while in the drawings tnere are illustrated. the preierrecl embodiment" any invention, it is to be unclerstoocl th re structural elements are susceptible such changes, in

shape and manner of assemblage, as fall ithin the scope of the appended claim.

. Villa}; Iclaim is:

A latch mechanism comprising a face,

jyplate adapted for attachment toa door, a H casingcarried' by said face plate, a laterally disposed latch member shiftable ini sa'id casing; a pivoted lever carried by said face 'plate and loosely engaging in the upper'edge H) of said latch member to facilitateshifting said latchmember; 'a'hoek'cai ried by said latch member and terminatln in asbeveled bill; a keepe y adapted to. 1"ece1ve the bill of lower edge thereof said hook and allow lateral movelnent of I said hook Without said bill becoming disen- 5 gaged' from said keeper, and means carried by said face plate and engaging in the latch member normally retracted.

In testimony whereof I afilx myslgnature I 20 in pi esence oftwo wltnesses.
